When buying tickets for the Moscow show, you have a choice between the "FAN-ZONE" (?), standard pit ticket, and seats. Whatever this FAN-ZONE is, it costs $135USD, whereas a pit ticket is $70USD. Seats range from $25-$50, depending on where the seat is located. We haven't really figured out what the FAN-ZONE is yet.
In Saint Petersburg, seats are $60, FAN-ZONE tickets are $40, and general admission is $30.
Public sale of the tickets was originally scheduled for May 19, but as of this posting, the sale date was pushed back to next week.
